Check for and expose maximum (DMA) transfer size Topic is solved
Posted: Thu Oct 13, 2022 5:26 pm
STM32 hal_spi_lld has an assert which checks that the maximum transfer size is not violated (n < 65536). Other drivers that use DMA also have this limitation, but this condition is not being checked. Additionally, it would be useful to remove that magic number and instead expose that as a #define so that the application can use it to split up transfers in blocks when needed.
